IMPROVEMENT IN CAR-AXLE BOXES.

Specification for'ning part of Letters Patent NO. 212179, dated. February 11, 1879 application filed November 9, 1878.

To all whom it may concerns Be it known that we, GEORGE WILKEs and ALEXANDER. Pour, of Monroe, in the County of Jasper and State of Iowa, have invented a new and useful Improvement in Anti-Frietion J onrnal-Boxes, of which the following is a specification, reference being had to the accompanying drawings.

Letters Patent of the United States were granted us, bea-ring date December 26, 1876, for anti-friction journal-boxes, and unbered 185,?11.

This application is for improvenents thereon. We have found by experience that certain changes in the original invention are advisable, which changes form the subject of this specification.

Figure l is a central longitudinal section of our journal-box as improved. Fig. 2 is an end elevatio'n of Fig. 1. Fig. 3 is a transverse section on line m x of Fig. l.

Referrin g to the drawings, letter A is the external casing of the journal-box, which, as shown, is adapted to a ear-journal. It is provided on its upper inner surface with two ribs,

a a Figs. l and 3, to receive and secure the inside lining. Its outer or more accessible end is closed with a cover, U, Secured by two bolts and nuts, c c, Fig. 2. lt is 'provided with an orifice, (I, Fig. l, for oiling purposes, closed with the hinged Shutter D. Thus that end of the box is closed almost, if not quite, dust-tight.

The aperture at the other or inner end of said outer casing is closed with a slide, u, as in my former application. The inner casing, B, consists of -two portions, divided as in the forner application. The npper half, as viewed in Figs. 1 and 3, fits between and is held in position by the ribs a a on A, and by inserting its lower edge in a rabbet in the lower half ot' the casing, as shown at s s, Figs. 3. Ribs e e upon its sides bear on the interior of the outer case, and prevent any'notion in that direction. An oil-hole at A, and opposite D, permits the lubrication of the inovng parts.

The lower half of the inner casiog, B connects with the upper half aforesaid. It is provided with a channel, f, Fig. 3, to receive the wedge or key F. This channel is deeper at the end nearer C, and gradually lessens im' depth to.nothing at the end opposite C, as will appear from the dotted line in Fig. 1.

The ends of the lower and upper halves of the inner casin g are raised so as to form a receptacle to contain oil. Thus each roller is frequently imnersed in the oil, of which there is no loss by leakage, and no cotton-waste is required.

XV hen the halves of the inner casing are united, as shown in Fig. 3, they form the sides of a cylindrical orifice, to receive our antifriction journal, just as in our former application, except that a rib within the interior is omitted.

A wedge, F, the form of which will clearly appear from the drawings, is inserted in the channel f. This, when driven home, bears against the lower part of outer casing, thus firmly looking the halves of the inner casing together, as well as foreing it into rigid connection with the outer casin The wedge is kept in place by the door C, and a pin, p, thrust through the shorter extremity of F, and two lugs, k k, cast on the outer casin l/Vhen our invention is applied to shafting with enlargements or shoulders thereon, or at or near the middle of a shaft, the frietion-bearing, con sisting of the rollers Gr and its hinged frame H, difi'ers in nothing from our former application, except that the rollers are now made with smooth and parallel surfaces, the groove formerly made in each of them to engage with a rib in the inner casing being omitted.

Our invention shown in Figs. l, 2, and 3 is applied to and removed from the axle as follows: First, the door G is removed by loosening the nuts c c. The wedge F is then withdrawn, which allows the inner casing, B, to drop down. The inner casing is then removed h alt' at a time. The friction-bearing, eomposed of the rollers and annular frames, is opened at the hinge by withdrawing the loose bolt i, Fig. 3, opposite the hinge. It is then removed froni the inner easin 2 The slide u is also removed. The axle E is then insert-ed, the frietion-bearing is introduced within the case and clasped around the axle, and the loose bolt i' is replaced, as heretofore. The upper half of the inside lining is inserted so that it covers the anti-friotion bearing, and then the lower half. The slide u is then closed and secured by' button o. The wedge F is inserted and pinned. Then the door C is bolted on, and the hinged Shutter D is then opened and oil introdneed at t, if it has not been done before.

The method of using the modification has already been suffieently described.

What we clain as new, and desire to patent, is

1. The onter cnsing, A, with the ribs a a, in combination with an inner casing, B, inolosin g ahinged anti-frietion journal, snbstantially as described.

2. The inner cesing composed of an upper and lower portion, in which the lower portion is provided with en inolined slot, in combination with the wedge or key F and the exterior cesing, A.

In testimony that we claim the foregoing improvement in anti-friction journal-boxes, as above described, we have herennto set our hands this 2d day of November, 1878.
